I have owned a camry hyrbid fully loaded for almost 3 years. I have already ordered my FFH but only just drove it yesterday. Here is what I noticed.
Acceleration. Although the car and driver report shows the camry with a pretty significant 0-60 advantage, there was not a noticable difference in my driving and the FFH had good acceleration
Room. The Camry has a tad more internal space I think but the FFH has much nicer seats and a lot more trunk room
Technology. the FFH "gadgets" and quality of its dashboard (both the nav system and the lcd readouts) are superior. the camry is cheap and not very aesthetically exciting
MPG. FFH is better here but i have no experience in the FFH long term. In the city, my Camry only gets about 34-35 at best. On the highway, I can get 38-39
Electric acceleration. The one thing i noticed right off the bat, was the FFH had significantly more electric acceleration than the Camry. The camry can't really acclerate without the gas motor helping unless its on a slight decline.
